I do not think San Paulo is one of the worst cities, good neighbourhoods (not downtown), fantastic restaurants and hotels, the main problem are the traffic jams during the week, every family have two or three cars… Downtown SP is a nightmare because of drug addicts but look at other cities in the world like Philly..

I live in Jardins, fancy boutiques, bakeries, nice places to eat, you can walk and walk, or use a biycle, enormous shopping centers with products from all over the world and a huge financial district…look at the decrepit commercial real estate in Manhattan…and try to rent an ofice space in Rio or SP…more expensive and difficult to find!
